The upper plate 12 has a plurality of upper perforations 12a having a plurality of lower perforations 14a and a spacing between adjacent lower perforations 14a that is less than the spacing of adjacent upper perforations 12a of the upper plate 12. Further, the upper plate 12 and the lower plate 14 may be designed to include the outer frame 16, that is, the upper plate 12 and the lower plate 14 are collectively combined to form a rigid body having a hollow chamber. The signal wires 18 are disposed between the upper plate 12 and the lower plate 14 in a non-contact manner, because the upper perforation 12& spacing of the upper plate 12 is greater than the spacing of the lower perforations 14a of the lower plate 14 Both ends of the signal line 18 are formed by bending to pass through the corresponding perforation 12a and the inverted perforation (4), and the two ends of the signal line 18 are separately disposed on the upper plate 12 and the lower plate 14 The outer surface of the solder joint 20 is connected. The insulating layers 22 are each covered with a corresponding signal line 18. The hybrid anti-matching structure includes a ground line 24 and a plurality of conductive units in the form of a circular tube 26 as an example. The towel, the grounding wire 24 is sprayed through each other - the corresponding upper perforation 12a and a corresponding lower perforation Ha are respectively connected to one of the pads 20 and electrically connected to the ground potential; the ® tubes 26 respectively The corresponding signal line 18 is disposed, and each of the tube body 26 and the service signal line 18 has the edge layer 22 'easy to say' the insulating layer 22 is such that the signal line 18 and the round tube body 26 are electrically connected. isolation. The surface of each of the round tubes has a conductive structure such as a metal surface. The conductive paste 28 is a layered structure and is respectively disposed on the inner surface of the upper plate 12 and the lower plate, and is simultaneously connected to and in contact with the ground line and each of the round tubes, so that the round tubes 26 are also electrically Connected to ground potential. It should be noted that the purpose of electrically connecting the grounding wire 24 and the tubular body 26 can be achieved when the single conductive cymbal 28 is disposed on the inner surface of the upper plate 12 or the lower plate 14. The colloid 3 has no conductive property, and is filled between the two conductive capsules to support the signals, the lines 18 and the impedance & structure, and the impurities are not easily shaken. The above is the structure description of the various parts of the m-switching module of the face pin. It is installed between the circuit board and the plurality of probes (Figure 12). The circuit board and space conversion module The combination of 1〇 and complex probes constitutes a local frequency probe. _ is set on the upper board 12 appearance _ number bribes (10) respectively with the circuit (four) s峨 contact and ground contact electrical connection, and set the next board The plurality of pads 2G on the outer surface of the 14 are respectively electrically connected to the corresponding probes for electrical transmission purposes. The ❿ is also subject to the technical interference that the spacing of the upper perforations is larger than that of the lower perforations 14a, so that the high impurity The contact distance between the majority of the probes of the needle card is reduced, and the electrons to be tested with a small pilot pitch can be determined in advance. The outer circumference of each of the signal lines 18 is set to a round body %. And each of the structural bodies is electrically isolated from each other. Each of the circular bodies 26 is electrically connected to the grounding wire by the conductive paste 28 and electrically connected to the ground potential.

The effect is also shown in Fig. 2, which is a high-frequency probe space conversion module 32 of the second creation of the present invention, which has the same components as the above-mentioned first preferred embodiment, and the difference lies in: The space conversion module 32 of the preferred embodiment is not provided with the two conductive adhesives 28 disposed on the inner surface of the upper plate 12 and the lower plate 14, and is directly injected into the metal to be gold. The purpose of the electrical connection between the grounding wire 24 and the respective tubular bodies 26 is achieved by the manner of the bonding board M. The metal glue or the bismuth metal powder simultaneously has the effect of stabilizing the signal lines 18 and the impedance matching structure. In this embodiment, the metal glue 34 is taken as an example. The conductor is continued. The third preferred embodiment of the high-frequency probe inter-work conversion module 36' has the same components as the second preferred embodiment described above. The difference lies in: The space conversion module 36 of the second preferred embodiment does not have the circular tube S 26 disposed outside the signal line 18, but retains the insulating layer 22 to cover the signal line 8 and then the upper layer 12 and the lower portion. A f-unit, such as a metal glue or a metal powder, is injected between the plates 14. The gold scale or the metal powder is in contact with the ground line 24 and electrically connected to the ground potential, and the sacrificial line 18 produces a good impedance. The matching fruit 'simultaneous' metal glue or metal powder has the effect of stabilizing the signal line 18 and the ground line 24. In the present embodiment, 'the metal glue 38 is taken as an example as the conductive unit.

When the upper plate 42 and the lower plate 44 are metal glue% (or metal powder), the external portion of the signal line 18 may be provided with the insulating layer 22 and the circular tube body 26 as shown in FIG. 2 or as shown in FIG. If there is only a layer of insulating layer between the upper plate and the lower plate 44, then the signal line α must have an insulating layer 22 outside the tube body 26, and the tube body is closed. The surface is in contact with the upper plate 42 and the lower plate 44 made of a metal plate to form a connection to the ground potential. Of course, in order to ensure a good connection effect, the upper plate 42 and the lower plate 44 may be disposed as shown in FIG. The inner surface_conductive paste 28 is connected to the ground line 24.
